Abstract
High pressure investigations of Bal2 yielded a new polymorph, which could be quenched and characterized by X-ray methods. PbCl2-type Bal2 is converted to an anti-Fe2P-type structure with more regular coordination polyhedra and an increase in effective coordination numbers. We discuss changes in bonding type by comparing the Madelung part of lattice energy in the two polymorphs.
